Patent JP-2004531972-A (JP)
IPC: H03M13/29
Filed: 2002-05-31
Abstract: Methods and apparatus for decoding codewords (902) using message passing decoding techniques which are particularly well suited for use with low density parity check (LDPC) codes and long codewords are described. The described methods allow decoding graph structures which are largely comprised of multiple identical copies of a much smaller graph (1000). Copies of the smaller graph are subject to a controlled permutation operation (904) to create the larger graph structure. The same controlled permutations are directly implemented to support message passing between the replicated copies of the small graph. Messages corresponding to individual copies of the graph are stored in a memory and accessed in sets, one from each copy of the graph, using a SIMD read or write instruction. The graph permutation operation may be implemented by simply reordering messages, e.g., using a cyclic permutation operation, in each set of messages react out of a message memory so that the messages are passed to processing circuits corresponding to different copies of the small graph.

Abstract: A luminaire has a plurality of reflecting lamellae between side reflectors. The lamellae each have an outer edge, an inner surface facing away from the outer edge, and a plane of symmetry through the outer edge and the inner surface. The lamellae have a resin body and a recess in the inner surface, in the plane of symmetry. The recess has a bottom surface transverse to the plane of symmetry and substantially parallel walls along said plane. The recess may widen stepwise from the bottom plane towards the inner surface. The lamellae, as compared with metal lamellae, provide a greater freedom to choose their shape and are less expensive. They nevertheless avoid the occurrence of reflections on the side reflectors, which cause unpleasant bright spots within the cut-off angle of the luminaire. A lamellae grid suitable for the luminaire has strips interconnecting, and integral with, the lamellae.

Abstract: The invention relates to a balun transformer for converting an unbalanced signal into a balanced signal or vice versa and having a bandpass characteristic for bandpass filtering the signal being converted. Such balanced transformers are substantially known in the art and comprise a first electronic circuit for transceiving the unbalanced signal and a second electronic circuit for transceiving the balanced signal wherein the first and the second electronic circuit are non-galvanically coupled via coupling elements. It is the object of the present invention to reduce the size of such known balun transformer. This object is achieved by embodying both electronic circuits as individual resonance circuits 100 - 1, 100 - 2 being operated at their individual resonance frequencies representing the centre frequencies of the bandpass filter characteristic. Each of the individual resonance frequencies is preferably set-up by adjusting a tuning unit ( 110, 120 ) and/or at least one dimension of the coupling element (CPL 1 , CPL 2 ) of its co-ordinated resonance circuit ( 100 - 1, 100 - 2 ) under the consideration that the length of each of the coupling elements (CPL 1 , CPL 2 ) must be shorter than lambda/4.
